Febuary 25th whole unit midterm to cover material
Midterm next week, lesson on Friday to prep for midterm. 5:30-7pm.
- A 3 kg block on a frictionless surface explodes into two pieces. One 1 kg piece moves right at 6 m/s. The second 2 kg piece moves at an angle θ above horizontal at 3 m/s. What is θ?
- Two identical 2 kg carts collide. Initially, cart A moves right at 3 m/s while cart B is at rest. If after collision they move apart at 1.5 m/s each, which statement is correct about the collision?
- In a car crash test, a 1000 kg car moving at 15 m/s hits a barrier. The crash takes 0.2 seconds, and the force applied by the barrier increases linearly from 0 N to its maximum value, then decreases linearly back to 0 N over equal time intervals. If the car stops completely, what was the maximum force applied?
- A 2 kg block initially moving right at 3 m/s hits a spring and bounces back left at 2 m/s. If the collision took 0.1 seconds, what was the average force exerted by the spring?
- A 2kg cart at rest is pushed by a spring (k = 400 N/m) compressed 0.3 m. The cart travels up a frictionless ramp inclined at 30° to the horizontal. What maximum height does it reach along the ramp?
- A 4 kg block slides down a 3-meter long ramp inclined at 25° with coefficient of kinetic friction μₖ = 0.2. If it starts from rest, what is its speed at the bottom of the ramp?

Review packet will be sent out before tomorrow! Midterm is over Openstax chapters 1,2,3,4,5,7,8. The homework is to find 7 FRQ's (one per section) from the AP section (how to find below), and do them. Then come to class with questions on them

Kids were at MIST, reduce the homework amount to half so they do it by class. Make announcement on classroom
